Spectra of Calcium Gas Discharge

The following image is color coded spectra of calcium undergoing electrical discharge excitation.

It is computed and plotted in your browser by a Java program which reads a file containing a list of emission line wavelengths and their corresponding strenghts.

Note: This program generates deep 24 bit color plots, therefore you may need to increase the color depth of your system to view subtle details in these spectra.

There may be a small delay as each Applet loads it's element emission line file and computes the spectra...

Here is a lower quality jpeg of the spectra:


Both neutral and singly ionized calcium contribute to the emission lines in this spectrum.

Calcium Spectra in Two Parts:

from 4000 to 5500 Ångstroms
and from 5500 to 7000 Ångstroms
